Geothermal Installation
Lake Area Heating & Air brings geothermal technology to Clay & Putnam County homes. A geothermal heat pump taps renewable ground energy for heating and cooling—more stable than air temperatures and more efficient than conventional systems. Our 18 years of HVAC experience includes design and installation of geothermal systems for residential properties. We partner with American Standard, Gree, and other brands to match the right system to your home’s size and geology. Whether you’re replacing an aging furnace, upgrading to a high-efficiency system, or building new, our team walks you through sizing, installation, and how to maximize your home’s comfort year-round.
Why Choose Us
Since 2008, our family-owned operation has served Clay & Putnam County homeowners considering a geothermal system, which is a long-term investment tied to your home for decades. We understand the region’s climate and soil conditions, and we’re personally invested in every installation we complete. When you choose Lake Area, you’re working with neighbors who live and work here and who will still be here for your equipment’s warranty period.
We’re an authorized American Standard Premier Dealer and Gree Select Dealer, backed by top-tier equipment warranties and manufacturer support. Your geothermal investment is protected by trusted names and dealer-level accountability.
Geothermal systems require precise ground-loop design, drilling or excavation expertise, and careful integration with existing ductwork or radiant floors. Our technicians follow manufacturer specifications and industry standards so your system operates at peak efficiency from day one, whether we’re tying into forced-air ductwork or a radiant heating layout.
We install systems from American Standard, Gree, Ameristar, GrandAire, and Tempstar. Each brand offers solid warranties and long-term parts availability, and we service every unit we install for years to come, so the same team that designs your system is available for its ongoing care.
We start with a detailed site assessment to evaluate your home’s heating and cooling needs, soil conditions, and available installation space. You’ll understand the system, the installation timeline, and the cost before work begins.
Our veteran ownership reflects a commitment to professionalism, discipline, and service excellence. We take pride in completing every project on time and leaving your home in perfect condition.
Get Started
Our team can evaluate whether a geothermal system makes sense for your Clay & Putnam County home, taking into account your lot size, existing ductwork, and comfort goals. Fill out a quick form to get started, or call us to discuss your options. If a ground loop isn’t practical for your property, ask us about heat pump repair for your current equipment or a package unit installation as an alternative path to efficient year-round comfort.
Our Process
Step 1 of 5
We begin with a comprehensive walkthrough of your home and property. We assess heating and cooling load, measure available space for ground loops or outdoor units, evaluate soil and groundwater conditions, and review your existing ductwork. From this, we design a system sized precisely for your home and calculate the most cost-effective loop configuration (horizontal, vertical, or pond loops where applicable). This step typically takes 1–2 weeks and includes a written proposal with equipment specs, system performance estimates, and a timeline.
Step 2 of 5
Once you approve the design, we handle permitting with Clay & Putnam County authorities (geothermal drilling often requires specific permits). We schedule the drilling or excavation crew, mark utility lines, and prepare the outdoor installation area. Interior prep includes staging for ductwork modifications and identifying where the indoor unit will be located. This phase typically lasts 1–3 weeks depending on local permitting timelines.
Step 3 of 5
The drilling or excavation crew installs the ground loop system according to the engineer’s design. For vertical installations in smaller yards, they bore deep wells and insert U-bend piping. For larger properties, horizontal loops are trenched across available land. For pond installations, a closed-loop submerged in water serves the same function. Once loop trenches are complete, we test pressure and run a thermal integrity test to ensure there are no leaks. Backfilling typically completes in 1–2 weeks.
Step 4 of 5
Our technicians install the indoor heat pump unit (the compressor and heat exchanger) in a utility space—typically a basement, crawlspace, or closet. We run refrigerant lines from the loop to the unit, integrate it with your existing ductwork or radiant heating system, and install the thermostat. If your old furnace or HVAC system is being removed, we handle disposal. For homes transitioning from radiant heat or baseboard heat, we may upgrade ductwork or design a hybrid system. Testing ensures proper airflow, proper refrigerant charge, and correct operation in both heating and cooling modes.
Step 5 of 5
Before we leave, we walk you through thermostat operation, seasonal changeover, filter replacement intervals, and what you’ll see in your monthly energy bills. We explain how the system runs during the heating and cooling seasons, point out where the ground loop enters the house, and discuss the habits that keep geothermal efficient. You’ll receive a complete manual, warranty documentation, a service record folder, and our contact information for future service. We schedule your first maintenance visit 30–60 days after installation to verify all systems are operating optimally and address any questions.
Plans & Financing
Keeping your HVAC system running well takes more than a single repair call — it takes a plan. Lake Area Heating & Air offers both a maintenance plan and flexible financing to make that easier for Clay & Putnam County families.
Regular maintenance catches small problems in your Central AC, furnace, heat pump, or mini-split before they become expensive repairs, and it keeps your system running efficiently through Florida’s long cooling season. Lake Area Heating & Air’s maintenance plan covers both residential and commercial equipment.
Big HVAC repairs and replacements shouldn’t have to wait, which is why Lake Area Heating & Air offers financing through Wisetack. Applying is quick, and it lets Keystone Heights homeowners move forward with the system they need on a schedule that works for their budget.
Every new residential system comes with a 10-year parts warranty from the manufacturer.
For added protection, we now offer an optional 10-year labor warranty—giving you full coverage and long-term peace of mind. This labor warranty must be added within six months of installation, so if we installed your system within the past six months, you’re still eligible!
